A&B Components
--professionally manufactures and sells all kinds of buzzers. We have
two production lines: piezo buzzer and magnetic buzzer, both include the
self drive type, external drive type and SMD type.
(Magnetic Buzzer, Transducer, Mechancial Buzzer, Beeper,
Piezo Element, Buzzer, Transducer, Piezo Siren, Alarm.)
There are over one thousand specifications now, the complete dimensions
for you to choose, we can modify the length of the pins and the wires,
or even customize for your unique project.
     
About Specifications:
Rated Voltage: A magnetic buzzer is driven
by 1/2 square waves (V o-p).
Operating Voltage: For normal operating. But it is not
guaranteed to make the minimum SPL under the rated voltage.
Consumption Current: The current is stably consumed under
the regular operation. However, it normally takes three times of current
at the moment of starting to work.
Direct Current Resistance: The direct current resistance
is measured by ammeter directly.
Sound Output: The sound output is measured by decibel
meter. Applying rated voltage and 1/2 square waves, and the distance of
10 cm.
Rated Frequency: A buzzer can make sound on any frequencies,
but we suggest that the highest and the most stable SPL comes from the
rated frequency.
Operating Temp. : Keep working well between -30℃ and
+70℃.
How to choose:
Driving methods: AX series with built drive circuit will
be the best choice when we cannot provide frequency signal to a buzzer,
it only needs direct current.
Dimension: Dimension affects frequency, small size result in high frequency.
Voltage: Depend on V o-p (1/2 square waves)
Fixed methods: From the highest cost to the lowest- DIP, wires/ connector,
SMD.
Soldering methods: AS series is soldered by hand, the frequency is lower
because of the holes on the bottom.On the other hand, we suggest AC series
for the reflow soldering, the reliability is better.
